MF Ultralight NFC chips are basic and cheap chips as they are able to store a small amount of data such as one short URL or an ID. Thus, this type of NFC chip is particularly adapted to projects requiring a high volume of tag for a low cost, or for projects like identification systems which require small storage capacities.
